Baton Rouge, Louisiana – An unusually strong surge of Arctic air is expected to move into Louisiana beginning Thursday, bringing a sharp increase in frost and freezing conditions across much of the state while precipitation chances remain below normal through early next week.
According to the National Weather Service and NOAA’s Climate Prediction Center, Louisiana is forecast to see limited rainfall from Thursday through Monday. While rain chances remain low, temperatures are expected to fall well below seasonal averages, setting the stage for widespread overnight freezes and cold morning conditions that are uncommon for mid-January.
Northern Louisiana, including Shreveport, Monroe, Ruston, and Bastrop, faces the highest risk for multiple nights of freezing temperatures. Sub-freezing conditions may persist for several hours overnight, increasing concerns for exposed pipes, sensitive vegetation, and unprotected outdoor plumbing. Clear skies and lighter winds will allow temperatures to drop quickly after sunset.
Central Louisiana, including Alexandria and surrounding communities, is also expected to see an elevated freeze risk, with widespread frost likely during the coldest mornings. Farther south, Baton Rouge, Lafayette, and Lake Charles may see temperatures approach or briefly dip below freezing in outlying and rural areas, while frost becomes more common away from the immediate coast.
Southeastern Louisiana, including the New Orleans metro area, may avoid prolonged freezes but will still experience colder-than-normal nights. Patchy frost is possible in inland sections, particularly north and west of Lake Pontchartrain, while daytime highs struggle to recover.
Even without precipitation, isolated slick spots could develop on bridges and elevated roadways during the coldest mornings along major routes such as Interstate 10, Interstate 20, Interstate 49, and Interstate 55.
Residents are urged to take cold-weather precautions, including protecting pipes, plants, and pets, and checking on vulnerable neighbors. This dry but unusually cold pattern is expected to persist into early next week, with freeze watches or warnings likely as confidence increases.
